Abstract: PROBLEM TO BE SOLVED: To provide a connector, which has the superior operability and which can securely install a flat wire. SOLUTION: When a turning member 4, which is provided in an opening part 6 opposite to an insertion hole 5 for flat wire 8, is positioned at a starting position of turning, a pressure-contact part 4b of the turning member 4 does not abut on the peripheral edge of a corner part 3a2 of a contact 3, and the flat wire 8 can be freely inserted and drawn, and the turning member 4 is operated for turning so that the pressure-contact part 4a of the turning member 4 pressurizes the peripheral edge of the corner part 3a2 of the contact 3 for elastic deformation, and a contact part 3a1 of the contact 3 pressure-contacts with the flat wire 8.  At the end position of the turning, the pressure-contact part 4b of the turning member 4 goes over a vertex P2 of the corner part 3a2 of the contact 3, and so that the force in the direction for maintaining the connecting condition is applied by the electrically restoring force of the contact 3.

Title: Heat exchanger consisting of a plurality of heat-exchanging pipes arranged parallel to one another
Inventor: TRAGE BURKHARD
IPC: F28F1/12
Filed: 1994-07-01
Abstract: PURPOSE: To suppress effect of contamination onto the heat transfer capacity of a heat exchanger by a structure wherein a fin has a plurality of openings having cross-sectional area larger than the conduction cross-section between two adjacent fins. CONSTITUTION: A heat exchanging tube 1 for passing heat exchanging medium has a width B larger than a height H and fins 3 are provided on the width plane 2. Each cross-section of an opening 9 is larger than the conduction cross- section between two adjacent fins 3. A flow passes through the opening 9 made in front of an obstacle S and moves to the cross-section formed by the fins 3 of adjacent heat exchanging tubes 1. Since the current velocity increases and a part of the flow can return back to the original cross-section through next opening 9 after detouring the obstacle S, the flow is eventually delivered uniformly from a heat exchanger. Consequently, local contamination or clogging of individual passage does not cause deterioration of heat transfer capacity.

IPC: H04L25/40
Filed: 1988-07-23
Abstract: PURPOSE:To receive a data of the start-stop synchronization system through the use of a general-purpose LSI capable of sending/receiving a continuous synchronizing system data by providing a means recovering a reception clock from the start-stop synchronization system data. CONSTITUTION:When a reception data RD inputted via an interface circuit 1 is fed to a charge point detection circuit 2, the data is sampled by using a clock pulse CLK from a clock generating circuit 4 and a reproduced reception data RD' is obtained. Simultaneously, the change point detection circuit 2 detects a change point of leading and trailing and a change point detection signal VD is given to a reception 1/n frequency divider circuit 6. The frequency divider 6 resets the CLK by using the VD and applies 1/n frequency division and the pulse subject to 1/n frequency division is fed to the general-purpose LSI 3 as a reception clock RC. Thus, the LSI 3 can receive the start-stop synchronization system data correctly by using the clock RC so as to reproduce the data RD'.

IPC: G03G21/10
Filed: 1991-06-26
Abstract: PURPOSE:To provide an image of high quality having excellent resolving power, sharpness, half tone reproducibility, and photographic reproducibility, by forming a cleaning blade out of organic material at least having urethane bond, and setting a relaxation quantity against stress of blade material over 30%. CONSTITUTION:The cleaning blade is formed out of organic material at least having urethane bond, and also the relaxation quantity against stress of the blade material is set over 30%. Hereat, the relaxation quantity as to stress is defined as a rate of a recovered quantity to an initial quantity of strain, when a certain tensile stress is applied on an object and then the stress is released. In this case, even if globular toner of particle size in narrow distribution is used, generation of breaking off of the blade 30 due to friction between the blade 30 and an image bearer 14 is sufficiently prevented, and poor cleaning is remarkably modified. Further, by specifying the ratio volume mean particle size to number mean particle size of toner in the range of 1.00-1.20, the image of high quality is stably obtained.

Filed: 1981-11-16
Abstract: PURPOSE:To have stable sensing in a device to detect the condition of objects electromagnetically etc., regardless of the type of the object and its environments, by controlling the timing to compare the sensed signals with the reference signal which has undergone correction. CONSTITUTION:Ultra-sonic signals received by a receiver 15 are converted into electrical signals by a piezo transducer PET1, placed into a DC converter 19 through an amplifier 17, half-wave rectified, held with its peak value, and put into the comparator 27 and reference value memory 21. This memory 21 makes impedance conversion of these signals and charges a capacitor C5 with them, forms the discharge time constant by resistances R11, R12, and divides so that they will become the threshold voltage in the comparator 27. When a transcript paper passes the ultra-sonic receiver and transmitter, the gain will drop by min. 12dB in the amount of signal reception, so that the level lowered by 6dB from the terminal voltage of the capacitor C5 after being divided will become the threshold value and DELTAVH1 and DELTAVL1 are relatively corrected, and further a stabilized sensing is obtained even though the DELTAVH2 and DELTAVL2 have changed by 3dB with respect to VL.VH.

Title: Air-conditioning controller for vehicle
Inventor: IIDA KATSUMI
IPC: B60H1/32
Filed: 1986-08-07
Abstract: PURPOSE:To improve the comfortability and to prevent fogging of glass, by turning a compressor on forcibly if said compressor is not turned on upon elapse of predetermined time after turning-off due to droppage of the temperature of blowout air from an evaporator below a turn-off temperature of the compressor. CONSTITUTION:Blowout temperature 10 of an evaporator 4 is inputted into a microcomputer 16. When said temperature 10 drops below a turn-off temperature of a compressor 8, the microcomputer 16 starts a timer while simultaneously turns the compressor 8 off thus stopping supply to the evaporator. When the temperature of the evaporator 4 exceeds over a turn-on temperature, the timer is reset thus turning the compressor 8 on. Even if the temperature 10 does not exceed over the turn-on temperature, the compressor 8 is turned on forcibly upon elapse of the time being set by the timer and the timer is reset. Consequently, the comfortability is improved and the degradation of drivability is improved.
